Efficient and environmentally friendly, ground source (geothermal) heat pumps use the stable, even temperature of the earth to heat and cool your home.

Ground Source Heat Pump Benefits:

  • Low-cost heating and cooling: Compared to other heating and cooling systems, ground source heat pumps typically cost less to operate.
  • Comfort & Convenience: Ground source heat pumps provide consistent indoor temperature and humidity levels.
  • Environmentally Friendly: Ground source heat pumps offer the potential to have zero greenhouse gas impacts when paired with a 100% renewable energy source. 
  • Low maintenance costs: compared to other heating and cooling systems, ground source heat pumps typically have lower maintenance costs.

Additional Details

A ground source heat pump takes advantage of the earth’s constant temperature to provide highly efficient heating and cooling. In the winter, fluid circulating in underground pipes carries the earth’s heat to your home, where it is then concentrated to provide heating. In the summer, the process is reversed and heat from your home is carried back to the earth through the pipes to provide cooling.

Ground source heat pump systems have three main parts:

  1. A closed loop, which circulates fluid through an underground field. The loop is enclosed in vertical and/or horizontal trenches.
  2. Single or multiple pumps, fans, and compressors that provide heating and cooling.
  3. A distribution system, typically ductwork, that carries air throughout the home to maintain an even temperature.

According to studies, ENERGY STAR® certified ground source heat pumps can reduce energy costs by 20 to 70 percent. A ground source heat pump is a reliable, low-maintenance, and environmentally friendly heating and cooling choice. It operates safely and quietly, with no combustion, direct emissions, or exposed outdoor equipment, such as a fuel tank. Because it is mechanically simple and all exterior equipment is below ground, protected from the weather, maintenance costs are often lower than other heating and cooling systems.

Eversource and UI residential electric service customers are eligible for incentives for the installation of a geothermal closed loop or direct expansion, packaged or matched coil/split* including water to water-designed types up to six tons per unit.

Geothermal equipment must be a closed loop or direct expansion type and ENERGY STAR® certified in order to be eligible for a rebate.

A list of ENERGY STAR certified geothermal equipment can be found on the ENERGY STAR website. You can also refer to the rebate application for equipment eligibility requirements.

The rebate for qualifying geothermal units is $750 per nominal AHRI-rated cooling ton for successfully commissioned geothermal systems (existing homes heating with electric or natural gas to a maximum rebate amount of $15,000 per home).  Oil & propane homes only - Rebate is paid in ½ ton increments capped at $1,500 per ton, up to $15,000 total rebate.

*Multiple sections and fans must be AHRI matched.
